Interventions
RADIATION
Genomically Guided Radiation Therapy
Participants will receive treatment 5 days per week, in once daily fractions. The total dose will be 50 Gy in 25 fractions or 42.56 Gy in 16 fractions with or without a boost of 10 Gy in 5 fractions to the cavity.

Primary outcome measures
Local Control
Time frame: At 3 Years
Local control will be defined as lack of progression in the ipsilateral breast as documented by response assessment imaging
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Participants should have undergone breast conservation therapy with a lumpectomy and axillary evaluation to consist of a sentinel node biopsy or axillary dissection
- Confirmation of Triple Negative (TN) breast cancer by tissue biopsy
- Adequate tissue to calculate RSI
- To fulfill the requirement of HER2- disease, a breast cancer must not demonstrate, at initial diagnosis or upon subsequent biopsy, overexpression of HER2 by either IHC or in-situ hybridization as defined by the ASCO / CAP Guidelines
- To fulfill the requirement of hormone receptor (HR)- disease, a breast cancer must express (\<10%), by immunohistochemistry (IHC), the hormone receptors (estrogen receptor \[ER\] and progesterone receptor \[PR\]) as defined in the American Society of Clinical Oncology (ASCO) / College of American Pathologists (CAP) Guidelines
- Life expectancy \>16 weeks
- Age ≥ 18 years
- Participants with surgery within 14 days should have recovered from all effects of
Where
- Clearwater, Florida

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
